37、1:2013 (E) 3 Introduction The search for ingredients of genetically modified origin is performed by means of the following successive (or simultaneous) steps. After sample collection, nucleic acids are extracted from the test portion. Extracted nucleic acids can be further purified, simultaneously o
38、r after the extraction process. Afterwards, they are quantified (if necessary), diluted (if necessary) and subjected to analytical procedures (such as PCR). These steps are detailed in the present and in the following International Standards: ISO 21569, Foodstuffs Methods of analysis for the detecti
39、on of genetically modified organisms and derived products Qualitative nucleic acid based methods ISO 21570, Foodstuffs Methods of analysis for the detection of genetically modified organisms and derived products Quantitative nucleic acid based methods Further information about definitions and genera
40、l items involving the steps cited above are collected in: ISO 24276, Foodstuffs Methods of analysis for the detection of genetically modified organisms and derived products General requirements and definitions. The International Organization for Standardization (ISO) draws attention to the fact that
41、 it is claimed that compliance with this document may involve the use of a patent concerning the PCR technology. ISO takes no position concerning the evidence, validity and scope of these patent rights. ISO has been informed that Applied Biosystems, Roche Molecular Systems, Inc. and Hoffman-La Roche
42、 hold patent rights concerning PCR technology. The companies have assured the ISO that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statements of the holders of these patent rights are r
43、egistered with ISO. Information may be obtained from: Licensing Department Applied Biosystems 850 Lincoln Centre Drive Foster City, CA 94404, USA and Roche Molecular Systems, Inc.

44、elements of this document may be subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights. DIN EN ISO 21570:2013-08 EN ISO 21570:2005 + AC:2007 + A1:2013 (E) 4 1 Scope This International Standard provides the overall
45、framework of quantitative methods for the detection of genetically modified organisms (GMOs) in foodstuffs, using the polymerase chain reaction (PCR). It defines general requirements for the specific amplification of DNA target sequences, in order to quantify the relative GMO-derived DNA content and
46、 to confirm the identity of the amplified DNA sequence. Guidelines, minimum requirements and performance criteria laid down in this International Standard are intended to ensure that comparable, accurate and reproducible results are obtained in different laboratories. This International Standard has
47、 been established for food matrices, but is also applicable to other matrices, e.g. feed and plant samples from the environment. Specific examples of methods are provided in Annexes A to D. 2 Normative references The following referenced documents are indispensable for the application of this docume
48、nt. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
